If you like the sound of the NAD, I don't think you'll like the Rotel. I had a NAD C317 (80w per ch I believe) and I absolutely loved it. I had it for about 10 years and decided it was time to upgrade. I auditioned the Rotel RB1582 amp (200w per ch) and the RC1580 preamp. I thought I liked my audition and bought them, only to find out they sounded terrible with my B&W Cm7's. For lack of a better term it sounded very bright and was painful to listen to at any level for more than 15 minutes. At first I thought it was my speakers, so I grabbed my old B&W 602's from the cellar and it sounded just as bad. A friend brought over his Rogue Cronus Magnum and it sounded amazing, just like my NAD. I ended up selling the Rotel gear and bought the Rogue Cronus Magnum which I still love today. I would not hesitate to buy another NAD either, and if I can find a deal on a nice used NAD integrated, I will buy another so I don't have to run the tubes in the summer. This is just my experience and opinion, but I would try and find something that sounds more like your NAD if you like it.
